Cash cow - Oli Forsyth

Just tennis all day, whenever you want.

Not many 13 year olds have that, do they? They're going to make you so good we won't recognise you.

Creating a tennis champion costs a lot; it requires time, dedication and, most importantly, cash.

Nina and Ade decide early on that their daughter is worth the investment.

Imagine the return - prize money, world travel, endorsements and maybe their own tennis academy.

Hell-bent on their child becoming Britain's number 1, the pair are willing to sacrifice just about anything.

If you want to reach the top spot in the game of tennis, love means nothing.

Oli Forsyth's breakthrough play is a blistering exploration of blind, parental ambition and the consequences of tough love.
